Attic Crew

Three things worth five minutes each before the weather turns.

One — the attic hatch. Run a hand along the edge. If you feel air moving, it’s unsealed.

Two — exterior foundation vents. Walk the perimeter. Any screen that’s torn, bent, or missing is an open invitation once the weather cools.

Three — the duct register in whichever room runs coldest in winter. Pull the cover, look inside. Dust and gaps at the seam mean conditioned air is leaking before it reaches you.

None of these need a contractor to check. All three are worth a photo for your own records, in case something changes later.

Save this before the first cold morning.

This gap is a quarter-inch. That’s enough.

As nights cool, rodents start looking for a way into anything warmer than outside. A quarter-inch gap at a foundation vent or utility pe*******on is passable for a mouse — half an inch for a rat.

Most homes have two or three of these without anyone knowing. None of them look urgent until October.

Save this before the weather turns.

Not a highlight reel — just the actual job. Ladders up, gear loaded, insulation moving through the hose, and someone checking every detail before it’s done. This is what a real attic insulation day looks like from the inside.

Before we book anything, these are the three questions almost everyone asks. What’s actually different about what you do? General inspectors glance at the attic access — we go all the way in, attic and crawl space, every time. Do I need to suspect a problem to book you? No — most of our customers just want a baseline, no suspected issue required. And if you do find something? Then we fix it, most small repairs happen the same visit, no separate appointment needed.

These are the same three issues our inspectors run into again and again: a duct seam that’s pulled apart, decades-old v***r barrier still sitting there doing its job (or not), and a rodent ‘fix’ that never actually held. If your attic or crawl space hasn’t had a full inspection, there’s a good chance one of these is up there right now.

Line 1 of a Walnut Creek report: hatch unsealed. Twenty minutes to close it.

The attic hatch is the single biggest, most overlooked air gap in most homes — a direct channel between conditioned living space and an attic that swings from 140°F in August to well under 50°F now that September nights are already cooling off.

Most hatches were never weatherstripped at install. It’s not a defect, it’s just a step that got skipped — and it’s the first place we check on every inspection.

This one took twenty minutes and a bead of sealant. Worth doing now, before the attic starts working against the house instead of with it.

Foil tape on attic ducts fails — slowly, over three to ten years depending on heat exposure. Once it lifts at a seam, conditioned air starts leaking into the attic before it ever reaches the register. We found this on a Bellevue duct run last week — one lifted seam, roughly four inches long, quietly venting cooled air into a 110°F attic all summer. Mastic doesn’t lift the way tape does. Brushed on, it cures hard and moves with the duct instead of peeling off it. Before you consider a bigger system, it’s worth checking whether the one you have is actually sealed.

Fremont. 1971 build. V***r barrier gone since before the current owners moved in.

The barrier was probably fine for its first fifteen years. Standard plastic sheeting from that era wasn’t built to last fifty. By the time we opened this crawl space, it had gone brittle and pulled away from the piers in six places.

No emergency. No rodents, no active mold. Just soil moisture with a direct path upward for longer than anyone in the house has lived there.

If your home is in this build era — Bay Area or Seattle — the barrier is worth a look before you assume it’s fine.

This attic went from contaminated to clean in two days — here’s every step, in order.

When rodents move out, what they leave behind doesn’t move out with them. Waste-soaked insulation keeps releasing contaminants long after the animals are gone — sealing new insulation over it just buries the problem under a fresh layer.

The order that actually works: remove the damaged material, vacuum and sanitize, seal every entry point with copper mesh and steel hardware cloth, then install fresh insulation. Skip a step and the fix doesn’t hold.

Six steps. Two days. One real fix.

Save this before any quote.

Your AC is fighting the sun. Here’s the layer that helps it win.

In summer, most of the heat in a Bay Area or Seattle attic comes from solar radiation through the roof. Standard insulation slows that heat once it’s already inside — but it doesn’t stop it from getting there.

Radiant barrier is a thin reflective foil that gets stapled to the underside of the rafters. It reflects 95% of radiant heat back out before it reaches your insulation. Attic temperatures can drop 20–30°F on peak days.

Install takes under a day for most homes — rolled out, measured, cut to size, and stapled directly to the rafters.

If your AC runs constantly during heat waves, the duct between the attic and your bedroom isn’t the only suspect. The roof above the attic is.
